This invention relates'to the construction of metallic frames for windows and the like, iprarticularly to metallic frames fashioned om sheet metal.

The object of my invention is to expedite assembling of the component perimetric parts which go into the making of metallic frames of the kind referred to, with a view toward securing such parts rigidly and per manently together at a minimum of expense as considered both from thestandpoint of labor-and material costs. v

How the foregoing advantages may be readily attainedin practice will be manifest from the detailed description whichfollows when taken in connection with the accompanying drawing;

Fig. I is a fragmentary elevation of the inside of a metallic window frame having its perimetric components secured together in accordance with my invention, certain portions of said frame being broken away and in section to expose important details.

Figs. II and III are fragmentary top and bottom plan views of the frame.

Fig. IVis a. vertical sectional view of the frame, taken as indicated by the arrows IV IV in Fig. I.

Figs. V, VI, and VII are perspective views of three different types of tab pieces by aid of which the component parts of the window frame are secured together.

The window frame herein delineated comprises a head or top rail 10, a sill or bottom rail 11, and jamb or side rails whereof only one is shown at 12 all components being fashioned to hollow angular cross-section from comparatively thing sheet metal after more or less common practice in this art. Each of the jamb or side rails 12 is formed with a guide groove 13 for the sashesnot illustrated, and the sill or bottom rail 11 wlth a double step 14, against which the lower sash is adapted to close.

To secure the several described perimetric components 10, 11 and 12, of the window frame together, I provide tab pieces which are respectively designated by the numerals 15, 16 and 17 in the assemblies of Figs. I- IV, and separately detailed in perspective in head rail 10 and the sill rail 11, at the forward corner and frontal side of the window frame. Asshown in Figs. .1, II and III, the length ofthe tab piece 15 is such asto fit substantially snug within the hollow. ofthe amb rail '12, at the regions above designated In placing each tab piece 15,1itsvertical flange 15b is buttedagainst the frontal wall of the jamb rail 12, with the outer face of its horizontal'fiange 15a flush with the end edge of said jamb rail, and with its tab 1500 projecting'therebeyond. In this position, the tab piece 15 is madefast to the j amb rail 12 preferably byspot welding its flange15b against the in side of said wall of thejamb rail. I

.,, The tab piece 16 of F ig. VI, is simply a flat oblong stamping; and I employ one such at each end of the jambor side rail 12 tosecure it to the head and sill rails 10, 11, at the inner corner and at the in side of. the window frame. 7 After placement in each instance intothe corner of the hollow of the j amb rail 12 at-the region indicated, with a flat side against the transverse jamb wall of said rail, the tab piece-16 is made fastalso preferably by spot weldinga short length being left to project beyond the end of the jamb rail 12to constitute a tongue 16% as shown in Figs. I and IV. V V

Like the tab piece 16, the tab piece 17 of Fig. VII is in theform ofa'flat stamping, but,- in this instance, of irregular profile configuration, that is to say: one of its side edgesis stepped as at 17a, while from its bottom edge depends a tongue 17%. From Fig.

IV-it will be noted that the tab piece 17 is used centrally of the juncture between the jamb rail 12 and the sill rail 11 atthe in or .jamb side, and that it fills theiwidth. of the sash groove 13 to the top ledge of said sill rail, with its stepped'edge 17a coinciding with the stepping of the sill at 14. The tab piece 17 is likewise preferably attached by spot welding to the jamb rail'12 with the tongue 17% extending beyond the end ofsa'i'd' rail. At properly allocated points, the head rail w and the sill rail 11 are provided with apertapes for reception. of the tongues 15%,". 16b5, and 17a: of the pieces'15,l6, and 17 within the ends of'the jamb rails 12. After assembuig the several components of the window, in the relation shown in Figs. I IV the tabs; 1503, 16m, and 17 w project through the aper titles in the head and sill rails 10,11 into the mlows of the latter where they are readily ieessible for the purpose of securing them. 'fihis 1 effect preferably by tack or are weld tag,- the result of the operation being confientionally indicated in the several instances as the letters lV, W and W VVhile I have specifically described my in- ;ve rition in connection with a metallic frame for a window, the same principle can, with attainment of like advantages, be embodied ih anetallic' frames for other purposes. From the foregoing it will be seen, moreover, that li 'have provided a very simple method and tews and the like comprising top, bottom, 5

- and side rail components of hollowcross-section; angle-section tabs at opposite ends of nieans for securing together the component tongues; projected into and secured fwi'tlnii the hollow of the sill rail, and all ofsa'iditabs affording means whereby the several-airs are permanently cofinectable into a rigid frame. 4.
